I couldn’t find definitive answers what the jumper actually disables. Of course, I understand that ME is still operational. me_cleaner removed modules and made ME stop before modules are loaded after initialising the CPU. So in my case it’s difficult to draw conclusions whether the jumper would suffice.</div><div id="m_1360324834895169854scrollbox"><br></div><div id="m_1360324834895169854scrollbox">I thought I should write to urge people check their motherboards for a similar jumper or switch.
